No CLI. No install. No dependencies. Markdown and folders. --- A chat forgets. FeatherSpec doesn't. You describe what you want, your agent turns it into a spec with testable acceptance criteria, then into a plan of baby steps — and only then writes code. Spec, plan, decisions and progress all live on disk as Markdown in your repository, so the next session, the next teammate, and the next tool pick up exactly where you left off. Nine /sdd- commands drive that loop, and they behave identically in Claude Code and in GitHub Copilot, because both tools execute the same files . --- Start in two minutes 1 · Get the template Click Use this template on GitHub — or clone it: The clone brings this repository's commit history along with a remote pointing back here. For your own project you want neither: delete the .git folder ( rm -rf .git , or Remove-Item -Recurse -Force .git in PowerShell) and run git init . Have Node.js? Then degit saves you that cleanup — it downloads only the current file state, so there is no history and no .git folder to detach in the first place: 2 · Open it in your assistant Claude Code CLAUDE.md imports AGENTS.md at session start, so the rules are always loaded.
